 |
|
Hi, all
I've got a Acer Aspire One D270 netbook, and install gentoo in it (Of course AMD64). It has 2GB memory installed by default, and I replace it with a ADATA 4GB memory.
Both livecd and installed gentoo show only 3GB recognized.
[code]
free -m
total used free shared buffers cached
Mem: 3002 74 2928 0 3 17
-/+ buffers/cache: 52 2950
Swap: 488 0 488
[code]
Does it have some limitation to the single memory slot or the motherboard chipset[/code]?
Thanks. |

what chipset does it use?
my eeepc uses the 945gm and it's limited to about 3GB... then again I only have one 2GB stick in the machine now...

The chipset is NM10. Does it only support 3GB max ? |

It has only one memory slot so looks like a 4GB stick gives 3GB effective memory is the best I can do.
Thanks! |

You're lucky you get even 3GB. My A110 (945 chipset) won't boot if there's more than 2GB in the machine. And since 512MB is soldered onto the board, the most I can have is 1.5GB.
PS. Good luck with graphics on that thing. You'll need it.  |
